| anterior median fissure of spinal cord | A deep median fissure on the anterior surface of the spinal cord. Synonym: fissura mediana anterior medullae spinalis, anteromedian groove, sulcus ventralis. (05 Mar 2000) |

| anterior median line | The line of intersection of the midsagittal plane with the anterior surface of the body. Synonym: linea mediana anterior. (05 Mar 2000) |
| palmar branch of median nerve | <anatomy, nerve> Branch of median nerve arising proximal to flexor retinaculum and running superficial to it to supply skin of proximal central palm and thenar eminence. Since it does not traverse carpal tunnel, it is not affected by carpal tunnel syndrome, even though it supplies skin distal to carpal tunnel. Synonym: ramus palmaris nervi mediani. (05 Mar 2000) |
| medial root of median nerve | <anatomy, nerve> The part of the median nerve coming from the medial cord of the brachial plexus. Synonym: radix medialis nervi mediani. (05 Mar 2000) |
| median | <statistics> Any value that divides the probability of a random variable in half, i.e. The probability of observing a value above the median and the probability of observing a value below the median are both less than or equal to one half. For a finite population or sample, the median is the middle value of an odd number of values (arranged in ascending order) or any value between the two middle values of an even number of values, in the latter case it is conventional to use the average of the two middle values. Origin: L. Medianus (18 Nov 1997) |
| median antebrachial vein | It begins at the base of the dorsum of the thumb, curves around the radial side, ascends the middle of the forearm, and just below the bend of the elbow divides into the intermediate basilic and intermediate cephalic veins; sometimes it divides lower down, one branch going to the basilic vein, the other to the intermediate vein of the elbow. Synonym: vena intermedia antebrachii, intermediate antebrachial vein, intermediate vein of forearm, median vein of forearm, vena mediana antebrachii. (05 Mar 2000) |
| median aperture of the fourth ventricle | The large midline opening in the posterior inferior part of the roof of the fourth ventricle, connecting the ventricle with the cerebellomedullary cistern. Synonym: apertura mediana ventriculi quarti, arachnoid foramen, Magendie's foramen, median aperture of the fourth ventricle. (05 Mar 2000) |
| median arcuate ligament | <anatomy> A tendinous connection between the crura of the diaphragm that arches over the aorta, forming the anterosuperior margin of the aortic hiatus. Synonym: ligamentum arcuatum medianum. (05 Mar 2000) |
| median artery | <anatomy, artery> Origin, anterior interosseous; distribution, accompanies median nerve to palm; anastomoses, branches of superficial palmar arch. Synonym: arteria comitans nervi mediani, arteria mediana. (05 Mar 2000) |
| median atlantoaxial joint | A pivot synovial joint between the dens of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas. Synonym: articulatio atlantoaxialis mediana, Cruveilhier's joint, middle atlantoepistrophic joint. (05 Mar 2000) |
| median bar of Mercier | A prominent band of fibromuscular tissue involving the interureteric ridge or neck of the urinary bladder, occasionally resulting in urinary obstruction. (05 Mar 2000) |
| median basilic vein | <anatomy, vein> The medial branch of the median antebrachial vein which joins the basilic vein. Synonym: vena intermedia basilica, median basilic vein, vena mediana basilica. (05 Mar 2000) |
| median cephalic vein | <anatomy, vein> The lateral branch of the median antebrachial vein that joins the cephalic vein near the elbow. Synonym: vena intermedia cephalica, median cephalic vein, vena mediana cephalica. (05 Mar 2000) |
| median cubital vein | <anatomy, vein> A vein which passes across the anterior aspect of the elbow from the cephalic vein to the basilic vein; commonly this vein is replaced by intermediate basilic and intermediate cephalic veins. The median cubital vein is often used for venipuncture. Synonym: vena intermedia cubiti, intermediate cubital vein, vena mediana cubiti. (05 Mar 2000) |
| median effective dose | The dose that produces the desired effect; when followed by a subscript (generally "ED50"), it denotes the dose having such an effect on a certain percentage (e.g., 50%) of the test animals; ED50 is the median effective dose, in radiation protection, the sum of the equivalent doses in all tissues and organs of the body weighted for tissue effects of radiation. The unit of effective dose is the sievert (Sv), epilation dose, the minimum amount of radiation sufficient to produce hair loss, usually in 10 to 14 days. (05 Mar 2000) |
